Vedclass · Answer

(A) The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.Visible light has a wavelength range of approximately $400 	ext{ nm}$ to $700 	ext{ nm}$.Using the relation $c = f \lambda$,where $c = 3 	imes 10^8 	ext{ m/s}$ is the speed of light,we can calculate the frequency $f = c / \lambda$.For $\lambda = 700 	ext{ nm} = 700 	imes 10^{-9} 	ext{ m}$,$f = (3 	imes 10^8) / (700 	imes 10^{-9}) \approx 4.29 	imes 10^{14} 	ext{ Hz} = 429 	ext{ THz}$.For $\lambda = 400 	ext{ nm} = 400 	imes 10^{-9} 	ext{ m}$,$f = (3 	imes 10^8) / (400 	imes 10^{-9}) = 7.5 	imes 10^{14} 	ext{ Hz} = 750 	ext{ THz}$.Thus,the frequency range is approximately $400 	ext{ THz}$ to $750 	ext{ THz}$,which aligns with option $A$.
